IMPROVEMENT IN RAILWAY-CAR BODIES.

Specification forming part of Letters Patent No. 127,186, dated May 28,1872.

Specification describing certain Improve ments in Gar-Bodies, inventedby ROBERT L. OMENSETTER, of the city of Philadelphia and State ofPennsylvania.

The object of my invention is the construction of car-bodies in such amanner as will prevent the collection of moisture in the joints of theframe work, more especially the joints of the Window-sills and the sillsof the bottom frame. In the ordinary construction of the cars, in stormyweather the rain beats into the joints of the Window-sills, and alsointo those of the bottom sills, and collects in the mortises and causesthe timbers to rot in a very few years. To obviate this evil I bisectthe lower sill, so as to make the ilues at each side of the windows andbetween the window-posts open at the bottom to prevent the collection ofWater.

Figure 1 is a side elevation of a section of a side of va car-body. Fig.2 is a vertical section at the line a a of Fig. l. Fig. 3 is a likesection atthe line b b and Fig. 4, a horizontal Section atvrtheV line cc.

Like letters in all the figures indicate the same parts". y

A A AA are the posts of the section. B B are sills,;;l etinto the innerand outer sides of the posts'at their lower ends, and confined theretoby means ot' screw-bolts. The tlues D at the sides of the windows andspaces beneath same are thus extended between the sills at C to thebottom of the car-frame.

It will readily be seen that the water which would otherwise collect inthe joints of the window-'sills and the lower sills, is allowed to rundown through the flues and pass oft' from the frame, so as to keep itperfectly dry, and thus prevent decay of the timbers incidental to theconstruction of the frame with single sills.

The forward movement of the cars creates a downward draught through thedues, which facilitates the passage of the water which may get inside ofthe ues; and also draws oft' the moisture from the timbers, and bykeeping them dry prevents the speedy decaying which usually occurs. Thedeiiecting-plates F are for the purpose of preventing dust passing upthe fines; but, as they are fully described in another application ofmine, a further description I deem unnecessary.

. I claim as my invention- The combination of the double sills B B withthe lower ends of the posts A, so as to extend the flues D to the bottomof the car-frame, substantially in the manner and for the purpose nabove set forth.
